If you do a "cryptsetup luksDump /dev/sdc" it will show you what the encrypted device was 
luksFormat'd with.

You can then do a "grep ^name /proc/crypto" and see what crypto algorithms are available.

You seem to have a mismatch.

The messages about access to /dev/bus/usb... is a puzzle.

Just to back up a bit...

Did you originally say you had an encrypted external hard disk you were trying to mount on 
your new machine but can't?  All this playing with thumb drives is just so you don't break 
the data on this disk while sorting out the problem?

I you could get a luksDump of the external disk that might help.
